PROFILE
Vidar Stiernström
In December 2024, Chris Stierns developed and integrated an explicit time integration solver for rate-and-state friction into the GEOS-DEV/GEOS repository. Using C++ and XML, Chris implemented a Runge-Kutta 3(2) method with a PID-based adaptive time-stepping controller, enhancing the physics solver framework’s ability to handle complex frictional behavior. The work included updating contact field definitions to ensure compatibility with the new solver and streamline data integration. By focusing on robust numerical methods and finite element techniques, Chris delivered a feature that reduces manual time-step tuning and improves simulation stability, demonstrating depth in both physics simulation and software development.

Dec 1, 2024December 2024 (GEOS repo GEOS-DEV/GEOS) focused on delivering a high-fidelity explicit time integration path for rate-and-state friction, with RK3(2) accuracy and PID-based adaptive stepping. The feature was integrated into the physics solver framework and the contact field definitions were updated to support the new solver. No major bugs were flagged as fixed this month; the emphasis was on delivering a robust solver and ensuring data-model compatibility.
